TOILET-PAPER CUTTER.

SPECIFICATION forming part of Letters Patent N 0. 604,150, dated May 17,1898. Application filed July 20, 1896- Renewed November 2, 1897. SerialNo. 657,208. (No model.)

To aZZ whom it may concern:

Be it known that I, JOHN HOBERG, Sr., a citizen of the United States,residing at Green Bay, in the county of Brown and State of WVisconsin,have invented new and useful Improvements in Toilet-Paper ToothedOutter's, of which the following is a specification.

My invention relates to improvements in devices for cutting paper, withespecial reference to the manufacture of that class of toilet-paperstrips having transverse cuts or lines of weakness formed at regularintervals therein.

In the preparation of the paper for market it is desirable for obviousreasons to cut or slit it while the same is in wide sheets, these beingafterward cut longitudinally to form the strips, and it is alsodesirable to cut alarge number of sheets at a time. The knives orperforators heretofore used have proved very unsatisfactory, both onaccount of the form of the slit or perforation and also by reason of thefact that they would often tear and destroy the upper sheets while beingwithdrawn.

The object of my invention is, first, to provide a form of cutter whichwill weaken the paper strip in a transverse zigzag line adapted. tofacilitate the removal of the sheets and which will not lift or tear theupper sheets while being withdrawn after making the out. In thefollowing description reference is had to the accompanying drawings, inwhich- Figure 1 is a top view of the paper-cutting mechanism, showingthe relation of my invention to the other portions of the machine. Fig.2 is a detail front View of my invention removed from the head-block.Fig. 3 is a view of the cutting edge. Fig. 4 is a crosssection drawn onthe line as so of Fig. 2 and showing my invention in relation to thebedplate and paper.

Like parts are identified by the same reference-letters throughout theseveral views. Referring to Fig. 1, it will be observed that the papersheets are fed in sets or blocks between rollers A, underneath thetransverse cutterB, and that the sheets so out are then fed into thepath of the disk cutters O, which divide the sheets into strips suitablefor use. Referring now to the remaining views, which show moreparticularly the form of my improved cutter, it will be seen that thesame consists in a flat strip or metal blade B, having its lower edgedivided at intervals by narrow recesses or cuts D, the edge of the bladebeing rounded between the recesses to form a series of teeth E and E, asbest shown in Fig. 2. The teeth E are of less width than the teeth E andare located in line with the rotating cutters 0, (shown in Fig. 1,) sothat the teeth E will cut across the line out by the cutters C. It willbe thus observed that the edges of the strip will be providedwith ashort out, which facilitates tearing it off in the right direction. Eachof the teeth E and E is provided with V-shaped recesses or troughs F ineach side, the troughs being formed to alternate from one side of theknife to the other and being out nearly through at the edge, thuscausing the edge of each tooth to appear as a zigzag line. (Best shownin Fig. 2.)

It will be observed that the recesses F extend upwardly from the edge ofthe blade to a sufficient distance so that its smooth upper surface doesnot penetrate the sheets, and the recesses thus facilitate thewithdrawal of the blade without lifting or tearing the paper, and. thecut formed in the paper is scarcely visible, as the fiber at the sidesof the cut is not disturbed. The sheets, however, will tear off morereadilythan they would with straight slits or perforations. The cutterso formed is bolted to a head-block G, which is given a reciprocalmovement by the machine used, the knife being formed to fit between thejaws of a die H, over which the paper is passed by the rollers, asheretofore explained. The knife is driven by the movement of thehead-block through the paper and between the jaws of the die with eachstroke, thus cutting all the sheets simultaneously.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A cutter for toilet-paper machines, comprising a blade subdivided byrecesses in its edge into a series of fiat teeth and having in the sidesof the teeth a series of V-shaped depressions formed to alternate witheach other on opposite sides of the blade and cansing the edge to appearin a zigzag line, in combination with means for causing said blade toreciprocate vertically and a die adapted to receive the blade as itpenetrates the paper, substantially as described.

2. A cutter for toilet-paper machines, comprising a blade formed withteeth E and E, each tooth having trough-shaped recesses or depressionsin the sides thereof arranged to form a cutting edge in a zigzag line incombination With a reciprocating head-block, for

actuating the blade, and a dielocated beneath the path of the paper andadapted to receive the blade as it penetrates the paper, substantiallyas described.

In testimony whereof I affix my signature JOHN P. REUTER, HENRY TENNIS.
